Titanium solubility in olivine in the system TiO 2 -MgO-SiO 2 : no evidence for an ultra-deep origin of Ti-bearing olivine

Hermann, Joerg; O'Neill, Hugh; Berry, Andrew


The finding of ilmenite rods in olivine from orogenic peridotites has sparked a discussion about the processes of incorporation and exsolution of titanium in olivine. We have experimentally investigated the solubility of Ti in olivine as a function of composition, temperature and pressure in the synthetic TiO2-MgO-SiO2 system. Experiments at atmospheric pressure in the temperature range 1,200-1,500 °C showed that the highest concentration of TiO2 is obtained when olivine coexists with spinel...[Show more]
